I am interested in finding Horst Stephan's Die Lehre Schleiermachers von der Erlösung (Tübingen, 1901), but it is oddly unavailable in the University of Chicago libraries. I would have thought that Brian Gerrish's presence at the Divinity School would have brought the volume to a bibliographer's attention at some point. I can't find a digitized version on Google Books, Europeana, Internet Archive, Hathi Trust, etc. either, which I had hoped would be a possibility because of the book's age.
I've ILL'd the volume and will hopefully get to see it before too long, but I've seen Stephan's work listed on a few bibliographies as recommended for research on Schleiermacher's christology, and so I'm a little concerned at how unreachable it is. I'll have to ask the library to look into buying it as well. Any used copies floating around for a reasonable price? Or reprints/digitizations that I've missed?
